I had been planning this for a while and got my two extra 12v power outlet connected today. I used a 30amp cube relay to disconnect the plugs when the power is off. And I also took the ground from the ground point on the back of the motor assembly, not the battery, and took the positive after a 30 amp fuse. I used all 10AWG wire and ran it though the firewall in the fat rubber grommet behind the battery. The wires are zip-tied high and tight to stay clear of the steering column and the relay and all the connections are behind the center dash panel, which is a no-tool access point. The plug pod was purchased from amazon for $15, search for “Iztor 12-24V car dual Marine Cigarette Lighter Splitter Power Adaptor Sockets and USB Charger” I will use this for heated blankets and a 12v heater/defroster. Which together will draw more power then the stock 12v plug can provide.

I also copied the upgrade from a post long ago (viewtopic.php?t=13097) and used the 175amp quick connector to the 12v battery to power a 1500w power inverter, for a “LEAF-TO-HOME” situation. I have a split-phase natural gas generator but its pretty loud, so I figure I can charge the car and power the house during the day, and then use the car to power the house at night. I do have a code complaint 10-circuit transfer switch, saying that just to head off the safety-patrol comments. I put the inverter in a suitcase to contain the wires and protect from damage. I did these two upgrades at the same time because one needed the other for the battery connection points.

I used the correct punch tool for the Anderson connectors and no solder. the correct tool must be used or it won't fit in the nice plastic housing. the positive jumper wire most visible in the photo was made with flattened 00 butt-splices that are soldered and heat shrunk, which is why they look flat. It worked out kind of better because I could drill the 8mm/10mm holes where I wanted. I used high dielectric rust-proofer to cover all exposed bolts.

None of these links are advertiser links that I get commission from, just linking to the source I bought from out of courtesy to the requestor. I did the work myself so there was no labor charges. Besides only your friend who is also mechanic would install this stuff anyway, too much liability for a professional shop.

The only thing I don't like about using the leaf as a power supply is the idle power draw.
If I remember correctly my leaf draws about 2 amps just to keep the DC to DC converter and inverter powered up while it's "on".
